To aZZ whom, it 72mg; concern:

Be it known that we, GEonc-n W. AKINs,

J one T.NELSO1\',and \VILLIAM Vnnuon, citi" .zens of the United States,residing at Nashville, county of \Vashington, and State of Illinois,have invented a new and ,useful Improvement in Cultivators, of which thefollowing is a specification.

The object of our invention is to secure a simple and eiibctivecultivator cipable of properly preparing the ground 011 either side ofthe CO1'1110\\' without injury to the growing corn.

Our invention relates to improvements in the axle-bar, the adjustment ofthe plow-beam thereon, and the operating mechanism for lifting andlowering the plows.

Figure 1 represents a perspective view of the improved cultivator. Fig.2 representsa plan view of the axle of the cultivator. Fig. 3 representsthe lower section of the crankaXlc box acting as the plow-beam hanger,showing plan of journal-grooves therein. Fig. 4 represents the uppersection or cap of the crank-axle box shown in Fig. 3. Fig. 5 rep resentsthe ring-band fitting around crankaxle bar and into recesses in thegrooves of said axle-box shown in Figs. 3 and 4. Fig. 6 represents theringband provided with setscrew fitting around erankaxle bar and intothe recesses of the grooves shown in Figs. 3 and l. Fig. '7 represents alongitudinal section of the crank-axle box shown in Figs. 3 and l, andsaid axle-bar moving therein. Fig. 8 represents the adjustable bridleconnecting the drag-beam to the frame. Fig. 9 repre sents the shovelat-tachment,which may be attached to the plow-beam in place of theplowshare shown in Fig. 1.

G is the frame resting on stand and the segmental rack-bar E is secured.G is the pole secured to seat-bar and frame. (Z is the link-leverconnecting the hand-lever F. to thelever-arin a, rigidly attached to theaxle bar.

In Fig. 2, 71. h represent the rectangularoffsets which carry theclearingarch and double cranks away from the line of wheel-spindles, soas to give greater elevation to the double cranks and clearingarch bythe rotation of the axle.

In Fig. 3,K represents the axle-box in which the double cranks arejournaled, the lower plate of the said box acting as the plow-beamhanger, the beam being secured to the under face by staplebolts throughopenings 10 and 11. it is the lower section of the journal groove,having recesses 3 and L therein, into which the bands 7 andS (shown inFi s. Sand 6) are loosely held. These bands preventthe lateral movementof the plow-beam on the axle by means of the set-screw 9, which passesthrough band 8 and impinges on the axlebar. The cap shown in Fig. at issecured in its place by means of a'staple-bolt countersunk in the upperface of the cap, and bolted to the lower plate through openings 2 2.{Shown in Fig. 3.) The slot 5 (shown in Fig. 4) isto provide room forthe movement of the set-screw 9, holding band 8 securely upon the axlewhen the axle rotates within the boxing by reason of the lifting orlowering of the plow-beam. Thej ournal-hanger K slightly tapers, growingsmaller toward the slotted end, the enlargement being vertically andintended to regulate the level of the plow when working in ground havinga sloping surface. This feature is shown in Fig. 7, where theregulatingscrew, passing through the cap at 3, is shown as applied.

In Fig. 8, L represents the adjustable bridle which connects theplow-beam B to the frame 0. This bridle is constructed in two pieceshinged together at 17 The lower arm of the bridle is loosely pivoted tothe plow-beam at 16. Its upper arm is loosely pivoted to asupportingbracket, 15, rigidly secured to the frame 0. The joint 17 ofthe bridle, acting as a hinge, allows a free movementup ward of the armsat the point of junction; but a downward movement out of a straight lineis prevented by the projecting foot 14-, said foot, when the two armsare in a line, being in contact with the upper end of the lower arm.

The function of this jointed bridle is to prevent the vertical movementof the plow-beam while plowing, and to adj ust itself by means of thejoint 17 to the movement of the beam when the plow is lifted from theground.

-We claim as our inventio1r 1. In a wheel-cultivator, an axle-bar havingtwo crank-bearings to carry the plow-beams, aclearing-archbetwcensaidcranks,andarectangular offset 011 the spindlesides of the bearing cranks, carrying said cranks and the clearing archaway from the line ofthe spindles, in combination with an opcratinglevcrand a frame, whereby additional elevationissecured to the clearing-archand double cranks by the rotation of the axle when the plows are raisedfrom the ground, substantially as set forth.

2. In a wheel-cultivator, an axle-bar having two double cranks, aclearing-arch between said cranks, and a rectangular oifset carryingsaid cranks and clearingarch away from the line of the wheel-spindles,in Combination with handlever F, link-lever d, rigidly-attached lebands7 and S, fitting therein, slot 5, and set i screws, whereby the lateralmovements of the plow-beam on the axle-bar are prevented and the plowadjusted for sloping ground, substantially as set forth,

4. 'In a wheelcultivator, in combination with a crankaxle, plow-beam,and frame, jointed bridle L, having brace-armsl2 and 13, jointedtogether at 17, and projecting foot 14, arranged and combined as shownand de scribed, substantially as and for the purposes set forth.
